I was reading this thread and thinking about the realities of preview and machines today. I then had a thought about how to marry digital and analog to give a preview deck for today.
If one had a tape deck with TC it would be a simple thing to drive the DAW with SMPTE and the appropriate offset and you could have preview, speed, who cares, as long or short as you want.
Now, unfortunately, most of our decks don't have a timecode track, so it becomes a little bit trickier. I leave it to you the reader to work out the details.
just a thought
